SPECIFICATION forming part of Letter s Patent No. 450,535, dated. April14, 1891.

Application filed November 13, 1890. Serial No. 371,349. (No model.)

To all whom it may concern..-

Be itknown that I, GEORGE A. SMITH, a citizen of the United States ofAmerica, residing at Paulding, in the county of Paulding and StateofOhio, have invented certain new and useful Improvements in Pumps; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which 1t appertains to make and use the same, reference being hadto the accompanying drawing, and to letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in force-pumps.

The object of the invention is to provide a pump which is simple andeffective in operation, and when operated will give a continuous flow ofwater from the pump-spout; and it consists in a pump in which thepiston-rod and pump-stock are alternately raised and lowered, said partsbeing connected to a common lever, the device acting both as a suctionand lift pump.

In the accompanying drawing, forming part of this specification, thefigure is a side view, partly in section.

A refers to the platform above the well or cistern,-to which is rigidlysecured a standard 3 B, acting as a fulcrum for a lever C. To the end ofthis lever the pump-stock or vertical pipe D is connected in anysuitable manner, and upon the other side of its fulcrum is pivoted thepiston-rod. The distance between the fulcrum and points of connection ofthe pump-stock and piston-rod may be varied according to the diameter ofthe stock or pipe and cylinderin which the piston works. The piston rodand pipe D pass through suitable 4 guides attached to the platform A,and the 'end of the lever is preferably connected to the pump stock orpipe D by means of a slotted band d, clamped thereon by a bolt, asshown. The lever, near its free end, carries an adjustable weight W,which acts as a counterpoise or balance for the weight of the pipe D.

To thelower end of the pipe D is connected a T-coupling F, to the lowerend of which is 5 secured a short section G, preferably rectangular incross-section, which contains a horizontal valve-seat to which ispivoted the valve g. Below the valve-seat g the section G has an openingG, over which plays a valve 9 opening inward. The section G is con-.nected by a curved pipe II to the cylinder I, in which plays the pistonc. This cylinder is also rectangular in cross-section, though it isobvious it may be cylindrical without depa rting from Inyinvention. Thecylinder I above the limit of the upward strokeof the piston is providedwith an opening I, covered by a valve i, which opens inward. The upperend -of the cylinder is closed by a suitable plug and packing, throughwhich the piston-rod plays. The cylinder I has a horizontal oifset withflanges, to which is connected a section K, carrying a valve 7.0, thissection being also connected to the T-coupling F by a union orotherwise.

The lever C adjacent to its fulcrum is provided with projections or lugswhich are adapted to abut against the standard to limit the oscillationof said lever, and when the lever is not provided with such projectionsbands are attached to the pipe D above and below the platform to abutagainst the same and answer the same purpose.

The parts G, K, and I are, .as heretofore stated, preferably maderectangular in crosssect'ion, the object of such construction being toprovide larger openings and valves than could be properly used were theycylindrical and of the same diameter.

In practice I prefer to have the lower portion of the pump submerged,and when the lever is reciprocated' the water will enter through theports G and I, and a few strokes will till the pump-stock D. On theupstroke of the piston-rod the other parts of the pump will descend, andthe water above the piston will be forced out of the exit-opening of thepipe. On the reverse stroke of the lever the pipe D and parts connectedthereto will be raised and the piston lowered, which forces the waterpreviously drawn into the connection II by the upstroke of the pistonabove the valve g and out of the exit'opening in the pipe D, thus givinga constant and unbrokenstream of water as long as the lever is operated.It will be noted that the water is forced as the parts are reciprocated,and that the valves are so positioned that the spaces above and belowthe piston are being filled While the opposite face of said piston isforcing the water. As the lever operates the piston-rod and rigid partsof the pump connected to the pipe D in opposite direc- 5 tionsthatis tosay. whilethe pipe D is movingup the piston-rod is moving downward thelength of thestroke of the lever is reduced one-half and the pumprendered doubly effective.

I am aware that prior to my invention it has been proposed to verticallyreciprocate the pump-tube and cylinder having a stationary piston-rod,and I do not. claim such construction as my invention, for it is obvious[5 that if the piston-rod in my present invention was held immovable theeffectiveness of the pump would be reduced more than onehalf, and itwould require more power to operate the same, the parts not serving tocoun- 2o terbalance each other.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination, in a pump, of a verti- 25 cally-movabledischargepipe carrying; and

having rigidly attached thereto valve-connec- 1 i l i tions G andK;"\vhieh communicate with a cylinder, the cylinder and connection G,having valved openings G and I, a piston-rod connected on one side ofthe fulcrum of an operatingdever and the discharge-pipe on the other,substantially as set forth.

The combination, in a pump, of a cylinder having a closed upper end, avalved opening above the limit of the upward movement of said piston, avalved tube connecting the upper portion of the cylinder with thedischarge-pipe, a connection or box G, having a valve g and avalve-opening G, and a pipe connecting the lower end of the cylinderwith the connection G, the pipe D, to which the aforesaid parts arerigidly connected, being connected to the piston-rod E, so that theparts will be alternately reciprocated, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE A. SMITH.
